Seismic
Interpretation - Overview
Seismic interpretation in WinPICS is quick and easy. The seismic
interpretation section is divided into nine main areas:
- Selecting
and Displaying Seismic – Learn how to select seismic
from your map or seismic window and display it in a new or existing seismic
window.
- Horizon
Picking – Pick horizons in your seismic window
and watch your posted horizon update dynamically in the map window. Use
one of four picking modes, including two automatic modes and two manual
force modes to pick your data. Use 3D volume picking to pick horizons
across the seismic volume. Quickly move through your seismic volume using
WinPICS hot-keys.
- Fault
Marking – Mark and edit faults on your seismic
data. Add fault branches to your main faults in areas of complex geology.
Interpolate faults quickly over the 3D volume using the 3D interpolation
function. Use WinPICS hot-keys to
move through your seismic volume. Calculate contact points and post them
to your map or slice displays.
- Fence
Displays – Create fences of 2D lines, in-lines/cross-lines,
and well synthetics to display data side-by-side in a seismic window.
This is useful for analyzing lie ties, comparing seismic versions, displaying
random traverses, or overlaying synthetics on seismic.
- Display
Options – Display instantaneous attributes,
adjust display interpolation, change display direction, and turn off labels,
timing lines, and scroll bars. Set the display mode (wiggle trace, wiggle
area, etc.), seismic gain, color palette, and wiggle decimation. Select
to flatten on horizon or copy and paste parameters from other seismic
windows.
- Synthetics – Create synthetics or stretch and squeeze existing
synthetics to better tie them with your seismic data.
- SEG-Y
Versions – Quickly switch between versions of
your data. View the processing history of the SEG-Y versions.
- Line
Ties – Apply interactive polarity, phase, amplitude, bulk shift, and
band-pass filtering corrections to your data. Use WinPICS
line tie diagnostics features such as cross-correlation and spectral analysis
and wavelet matching to better tie your seismic.
- Similarity
Mapping - Uses cross correlation coefficients for data pattern recognition.
